2 Claims.

This invention relates to what may be termed a boiler compound dispenser, the device being designed particularly for feeding a water-treating compound or solution to water being fed to a locomotive boiler.

In accordance with the present invention a device of the character described is provided for connection either directly to the locomotive injector or to the locomotive feed water heater l0 pump at the vacuum side thereof whereby the compound or solution will be drawn into the injector or the pump as the case may be to there 7 commingle with the water being fed to the boiler.

A further'object of thepresent invention is to provide a device of the character mentioned which is substantially automatic in operation requiring neither attention nor adjustment;

It will also be found in actual practice that the device will operate with equal eiiiciency on stationary boilers or any other type of boiler.

The invention together with its objects and advantages will best be understood from a study of the following description taken in connection with the accompanying drawings wherein:

Figure 1 is a view of the device with the compound reservoir tank and sight glass associated therewith shown in section.

Figure 2 is a sectional view through a chamber-forming assembly hereinafter more fully referred to. I

Figure 3 is a sectional View taken substantially on the line 3-3 of Figure 2.

Figure 4 is an elevational view of a window glass for the sight feed chamber shown in Figure 2.

Figure 5 is a sectional view through a window gasket and Figure 6 is a view taken substantially on the line 6--6 of Figure l.

Referring to the drawings by reference numerals it will be seen that in accordance with the invention there is provided a suitable tank 5 that may be conveniently mounted on the locomotive and is adapted to contain the water treating compound. The tank 5 at the top thereof is provided with a filling opening '6 for which a hinged door or closure is provided, the door 7 being provided further with a vent opening 8 as shown.

Also in order that one may readily ascertain the level of the compound or solution within the tank 5 there is provided for the tank a sight tube assembly 9 which includes a sight tube it of glass, or other transparent material, suitably connected with upper and lower fittings H and I2 that are tapped into one end wall or header plate of the tank 5 and are secured to said wall of the tank through the medium of jamb nuts l3 as shown. I

Extending into the tank 5 through a suitable I opening provided therefor in the top of the tank 5 is a suction tube M which at its inner end is bent into a substantial U, and at said end is provided with a screened inlet it,

At the outer end thereof the suction tube 54 is connected through the medium of a coupling i6 1 0' with a substantially L-shaped nozzle I1. I

The nozzle H is tapped. into the wall of a substantially cylindrical sight-feed chamber H5. The nozzle H is provided with a removable tip 99 through which the solution drawn into the cham- 5 her, l8 through the tube It from the tank 5 enters the chamber l8 in jet form. I

The chamber i8 is provided at the opposite ends thereof with sight windows, each sight window including a window glass 20 that has a dia- 20 metrically enlarged end 2i that is in abutting engagement with an internal annular shoulder 22 provided therefor inwardly from an end of the chamber I3; an end 23 of reduced diameter, and a tapered intermediate section 24. 25

Sleeved on the sections 23 and 2d of each window glass 20 is a packing ring 25 of rubber or other suitable material and having its bore, at one end thereof, flared as at 26 to conformably accommodate section 24 of the window glass. 30

The glass 20 and packing ring 25 are held in position within the chamber 88 through the medium of an aforementioned internal shoulder 22 and an annular follower 2'! that threads into the end of the chamber as clearly shown. 35

In connection with the above, and as clearly shown in Figure 2, the sight window assembly is duplicated at each end of the chamber i8.

Tapped into the chamber 68 intermediate the shoulder 22 is one end of a pipe section 28. Suit- 40 ably connected to said end of the pipe section 28 is an intake nozzle 2% provided with a suitable and removable tip 38. At the opposite end thereof the pipe section 28 is connected through the medium of an elbow or other suitable fitting 3! 45 with a nipple 32 a portion of which only is shown in the drawings and which nipple extends from the vacuum side of the injector or pump of a water feed system of a locomotive boiler.

It will thus be seen that in actual practice when 50 the injector or pump of the feed water system of a locomotive boiler is in operation the compoundcontents of the boiler 5 are, by vacuum, drawn into the tube it through the screen inlet l5 thereof passing through the tube and discharging 55 through the nozzle I1 into the sight-feed chamber I8. From the chamber I8 the compound is drawn into the injector or pump as the case may be, passing from the chamber l8 through the nozzle 29, pipe 28 and nipple 32 thereby supplying the water-conditioning compound to the Water being fed to the locomotive boiler.

In actual practice it will be found that the device will operate to feed the compound into the boiler in correct proportion to the water being fed to the boiler with the result that the boiler will be kept free from scale and consequently less fuel will be required for the eflicient operation of the boiler.

The device will also be found, in actual practice, to be a labor saver, to be substantially foolproof having practically no moving parts to get out of order; will permit injectors and boiler checks to be worked longer periods without shutdown, will lengthen the life of boiler flues, fire boxes, etc.; eliminate the expensive installation of water-treating stations and will not require mechanical knowledge for the control and operation thereof.

It is thought that a clear understanding of the construction, utility, advantages and operation of an invention of this character will be had without a more detailed description.

Having thus described the invention what is claimed as new is:

1. A device for use in connection with the feed water system of boilers for feeding a water-treating compound to the water being supplied to such boiler, said device comprising a receptacle for the compound, a sight feed chamber remote from said receptacle, a suction line extending from the receptacle to said chamber, a nozzle at the discharge end of the suction line extending into the chamber through an upper portion thereof, a second suction line extending from the chamber and adapted to be connected with the injector of such system at the vacuum side of said injector, said second suction line having a part extending downwardly through the chamber to a point adjacent the bottom of the chamber and a tip connected with the lower end of said part and having a reduced bore therein.

2. In a boiler compound dispenser, a chamber including a horizontally arranged tubular member having internal annular shoulders spaced apart and spaced from the ends of the tubular member, said ends of the tubular member being internally threaded, a transparent plug fitting in each end of the tubular member, each plug having an enlarged inner end resting against one of said shoulders, a reduced cylindrical outer end and a tapered intermediate part connecting the reduced outer end with the enlarged inner end, an annular gasket fitting around the reduced outer end of each plug with its inner end bearing against the tapered portion, an annular follower exteriorly threaded to engage the internal threads at each end of the tubular member with the inner end of the follower engaging the gasket, a supply pipe having a portion entering the tubular member at an angle in the upper portion of the tubular member and between the shoulders, a nozzle extending into the tubular member and connected with said part of the supply pipe, an outlet pipe entering the top part of the tubular member between the shoulders, a

tubular member connected with the inlet end of the last-mentioned pipe and extending to a point adjacent the lower side of the tubular member, and a tip in the lower end of the last-mentioned tubular member and terminating in spaced relation to said lower side of the first-mentioned tubular member, and means for connecting the discharge pipe with a suction producing device.
